ASH-SIFTER.

Specification of Letters Patent.

Patented Mar. 17, 1914:.

Application filed November 27, 1912. Serial No. 733,732.

To all whom it may concern:

Be it known that I, PATRICK Connor, a citizen of the United States,residing at Philadelphia, count-y of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Ash-Sifters,of which the following is a full, clear, and ex act description,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to that class of ashsifters in which an agitatablescreen is mounted in a box.

The object of my invention is to so construct the sifter that the ashesand cinders may be introduced to the screen, the sifting operationperformed and the ashes and cinders separately removed with theproduction of a minimum of dust.

In the accompanying drawings: Figure 1 is a plan view of my improved ashsifter; Fig. 2 a front elevation; Fig. 3 a partial end view; Fig. 4 ahorizontal section on line H of Fig. 2; Fig. 5 a vertical-section online 5-5 of Fig. 4c; and Fig. 6 a partial section on line 6-6 of Fig.4:.

The sifter box a is mounted on legs I) which rest on the floor. Thesifter box is provided with a top opening 0, over which rests a receiveror storage box cl having a hinged cover 6. Into the receiver is directlydeposited the cinders and ashes taken from the ash pit of the heater orfurnace. The receiver at is provided with a removable sliding bottom f,which normally closes communication between the receiver and the sifterbox. The receiver (Z is shown as removable. If desired the cover 6 maybe made integral with the receiver, and the receiver may be filled afterfirst inverting it and sliding back the bottom f. The bottom f may bethen closed and the receiver may I then be again inverted anddepositedin position over the sifter box. If, however, the cover 6 is hinged, thereceiver may remain permanently in position over the sifter box a, andthe ashes and cinders placed in the receiver while in that position.Extending within, and between the ends of, the sifter box a, and aboutmidway between the top and bottom thereof, are two horizontal supportingbars 9, upon which loosely rests the screen or sifter h. The ash box isalso provided with an opening a in the upper part of one side thereof.To the lower edge of this opening is hinged a door j which, when closed,forms virtually part of that side of the box. The door may be retainedin its closed position by means of any suitable latch, as 70. The door jis provided with a vertical slot Z, and a similar vertical slot at isformed in the opposite side of the box.

lThe screen 72, is provided with arms a, n,

which extend respectively through the slots Z and m. On the arm nprojecting through the slot Z is formed the handle 0.

The screen it may be agitated by grasping the handle 0 and rocking thescreen back and forth on its supporting bars 9', the screen being guidedin its movements by the bars rt, 77., in the slots Z and m. I have alsoprovided the following means for agitating the screen h, which may beemployed in case it is not desired to agitate the screen by directmanipulation of one of the bars 11.. Extend ing between the sides of thesifter box a, immediately below the hinged door j, is a shaft 10, oneend of which projects through one side of the box and has the crank g bymeans ofwhich the shaft may be turned.

The shaft is provided with the oppositely disposed cams 1, which, as theshaft is rotated, alternately engage the bottom of the screen It, oneside of the screen being engaged by one cam and the other side of thescreen being engaged by the other cam. This produces a rocking motion ofthe screen similar to that produced by direct manipulation of one of thebars a.

The sifter box a is provided with a sliding removable bottom .3.Underneath the bottoms, and preferably fairly closely fitting the sifterbox but not attached thereto, is a discharge receptacle 2?, which, whenthe bottom 8 is removed, receives the ashes which have passed throughthe meshes of the screen.

In the end of the box, preferably near the bottom, is a relatively smallopening a,

which is adapted to be closed by a door 4) but it may be brieflyoutlined as follows: The hot ashes and cinders from the' ash pit areplaced in thereceiver (Z in either of the ways hereinbefore described.The receiver is preferably made of suflicient size to hold several dayssupply. When it is desired to sift the ashes and cinders, the bottom 6of the receiver (Z is slid out to the extent required, dependent uponwhether it is desired to sieve all, or only a part, of the ashes andcinders in the receiver cl. The ashes and cinders thereupon drop intothe siftcr it. At this time the doors 7' and e and the removable bottom.9 are closed. The Sifter may then be agitated by either of the meanshereinbefore described, which causes the ashes to fall onto theremovable bottom 8, while the cinders remain in the sifter h. The aboveoperation is, if necessary, repeated, until all the material is sifted.The removable bottom .9 is then slid out and the ashes resting thereondrop into the discharge receptacle or ash-box 2,. After the removablebottom 8 has again been closed and the dust within the sifter box a hassettled down, the door j may be lifted, and the sifter 7t containing theseparated cinders, may be removed. The foregoing operation ispractically a dustless one. Further, the cinders are not discharged intoan exterior receptacle; but being scattered over the bottom of thescreen, the clinkers may be readily picked out by hand.

Having now fully described my invendesire to protect by 1 ing to permitthe removal of the screen, and

a door closing said opening.

2. In an ash sifter, the combination with a sifter box having an openingto receive the cinders and ashes, of a-screen supported within the boxso as to be free to rock, there being an opening in the upper part ofone side, a hinged door for the opening, there being a slot in the doorand a corresponding slot in the side of the box opposite the door, andarms on the screen projecting respectively through said slots, thereby.permitting the screen to be rocked and also allowing the door to open topermit the removal of the screen. v

In testimony of which invention, I have hereunto set my hand, atPhiladelphia, on this 23rd day of November, 1912.
